Here's how I see infinite regress: Two mirror face each other.
The image seems to go on for infinity. Infinite regress. But...
What is it really? It's a repeating loop. But.. what makes this
loop special or different? We're able to count how many times it
loops and traverse the counting. Not only can we traverse the
counting of the loops, but we can see all of the loops
simultaneously. Since our counting abilities are necessarily
limited, there's really no ending it. It's a counting illusion.
Our numerosity systems get rekt. It's also a dimensional
illusion. If you want to incorporate an infinity into a system,
just go up a dimension and the infinity becomes bounded by the
higher dimension. Also consider: If you are looking at a two
dimension image, you're not looking at infinite regress. You're
looking at a two dimensional image [which of course isn't
*really* two dimensional because that's a construct but that's
another tale) "Count"er this thought at will
